You want to start your offensive drive with as much field in front of you as possible. To do this, use your secondary controller and punt the ball to yourself, and run out of bounds near your own endzone.

Using your secondary controller, choose to control the defensive player that is in front of the "B" button receiver. Using your main controller, snap the ball and throw the ball to B when he gets wide open. After making the catch, you should be able to sprint down the field (using A), all the way to the endzone.
